How many electrons are in a mole?
1 mole of electrons contains the Avogadro constant, L, electrons – that is 6.02 x 1023 electrons.
What is one mole of an electron?
Since 1 mol electrons is 6.02214076×1023 electrons (Avogadro’s number), the Faraday constant is equal to the elementary charge e, the magnitude of the charge of an electron, multiplied by 1 mole: F = 96485.
How many moles are in 1 kg?
The idea here is that 1 kg-mole is equal to 103 moles. This is the case because a mole of a substance must contain a number of particles of that substance equal to the number of atoms present in exactly 12 g of carbon-12.
How is Faraday calculated?
The Faraday constant is defined as: F = I ∙t n The volume of hydrogen generated is converted to a number of moles using the ideal gas equation.
How many atoms do carbon have?
The value of the mole in precisely 12 grammes of pure carbon-12 is equal to the number of atoms. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 x 1023 atoms.

What is the mass of 1 mole of oxygen?
Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = 32 g.
Is chlorine a single atom?
2.8. Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
